Abstract

Although little is known about the etiology of progressive supranuclear palsy (PSP), genetic and epigenetic factors, oxidative injury and inflammation are thought to contribute to its development and/or progression. Evidence for activated glia involvement in PSP has raised the possibility that neuroinflammation may contribute to its pathogenesis. To investigate the correlation between neuroinflammation and PSP, a comparative study was conducted on the patterns of cytokine expression in different regions of the brains of PSP, Alzheimer's disease (AD) patients and normal controls. Our results show different patterns of cytokine expression in each disease, with the expression of IL-1β transcripts being significantly higher in the substantia nigra of PSP than in AD and controls, while AD brains had significantly higher IL-1β expression in the parietal cortex compared to PSP and controls. In addition, expression of TGFβ was significantly higher in the cortical areas (particularly frontal and parietal lobes) of AD compared to PSP and controls. These results show a disease-specific topographical relationship among the expression of certain cytokines (IL-1β and TGFβ), microglial activation and neurodegenerative changes, suggesting that these cytokines may contribute to the pathologic process. If so, the use of cytokine-inhibitors and/or other anti-inflammatory agents may be able to slow disease progression in PSP.

  • Gliosis and neuroinflammation are prevalent in tauopathy patient brains and recapitulated across many animal models.

    “Gliosis and neuroinflammation are prevalent in tauopathy patient brains [4, 5, 106] and recapitulated across many animal models [127, 170–174].”

    From Glial contributions to neurodegeneration in tauopathies (2017) · cites this paper as [106]

  • Several studies identified increased microglia number and activation in the substantia nigra pars compacta, subthalamic nucleus, pyramidal, extrapyramidal motor system, and cerebellar output of brain tissues from PSP patients by immunochemical postmortem analysis.

    “Several studies have identified increased microglia number and activation in the substantia nigra pars compacta (SNpc),372 subthalamic nucleus,373 pyramidal, extrapyramidal motor system, and cerebellar output374 of brain tissues from PSP patients by immunochemical postmortem analysis.”
  • Microglial activation, indicating neuroinflammation, is present in PSP.

    “However, neuroinflammation also occurs in PSP, with microglial activation5,6, with a proposed toxic alliance between tau-mediated neurodegeneration and neuroinflammation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
